ABSTRACT:
By the use of a binder comprising (a) 40 to 70 wt % of a water-soluble amide material and/or water-soluble amine material and (b) 25 to 60 wt % of a polyamide resin component substantially composed of a polyamide resin material having 10 carbon atoms or more on average between amido groups, a molded article is produced by metal powder injection molding.
From such a molded article, the water-soluble amide material and/or water-soluble amine material is eluted by a water-based solvent and then, the polyamide resin component is removed by heating.
